    • A stress distributing cross member hanger system for an aluminum boat trailer includes a welded bracket assembly on an aluminum cross member for bolting the cross member to an aluminum side rail. The side rail can be either I-beam or tube shaped with mounting bolt holes through its web or side walls respectively. The cross member can be either tube shaped or I-beam shaped with a pair of aluminum brackets welded to either side at each end. The paired brackets are bolted to the side rail at the bolt holes. The length of the weld and the weld pattern is selected to distribute the stresses thereby reducing weld failures.
    • 用于铝船拖车的应力分布横梁悬挂系统包括在铝横梁上的焊接支架组件,用于将横梁螺栓连接到铝侧轨。 侧轨可以是工字梁或管形,分别具有通过其腹板或侧壁的安装螺栓孔。 横向构件可以是管形或I形梁形,其中一对铝支架焊接在每一端的任一侧。 成对的支架用螺栓固定在螺栓孔的侧轨上。 选择焊缝的长度和焊缝图案以分布应力,从而减少焊接故障。

    • Effective in-situ injection technology for the remediation of dense nonaqueous phase liquids (DNAPLs) such as trichloroethylene (TCE) benefits from the use of decontamination agents that effectively migrate through the soil media, and react efficiently with both dissolved TCE and bulk TCE. A novel decontamination system contains highly uniform carbon microspheres preferably in the optimal size range for transport through the soil. The microspheres are preferably enveloped in a polyelectrolyte (such as carboxymethyl cellulose, CMC) to which preferably a bimetallic nanoparticle system of zerovalent iron and Pd is attached. The carbon serves as a strong adsorbent to TCE, while the bimetallic nanoparticles system provides the reactivity. The polyelectrolyte serves to stabilize the carbon microspheres in aqueous solution. The overall system resembles a colloidal micelle with a hydrophilic shell (the polyelectrolyte coating) and a hard hydrophobic core (carbon). In contact with bulk TCE, there is a sharp partitioning of the system to the TCE side of the interface due to the hydrophobicity of the core. These multifunctional systems appear to satisfy criteria related to remediation and are relatively inexpensive and made with potentially environmentally benign materials. An aerosol process is preferably used to produce zerovalent iron particles supported on carbon. A method of lubricating includes creating carbon microspheres produced from a monosaccharide or polysaccharide, the carbon microspheres having a diameter of 50 nm to 6 microns, coating the microspheres with a surface coating and using the carbon microspheres as a lubricant.
    • 使用三氯乙烯(TCE)等致密非水相液体(DNAPLs)进行有效的现场注射技术,有利于使用有效迁移通过土壤介质的去污剂,并与溶解的TCE和体积TCE有效反应。 一种新颖的净化系统包含高度均匀的碳微球,其优选地在用于运输通过土壤的最佳尺寸范围内。 微球优选包封在聚电解质(例如羧甲基纤维素,CMC)中,其中优选连接有零价铁和Pd的双金属纳米粒子体系。 碳作为TCE的强吸附剂,而双金属纳米粒子体系提供反应性。 聚电解质用于在水溶液中稳定碳微球。 整个系统类似于具有亲水壳(聚电解质涂层)和硬疏水芯(碳)的胶体胶束。 与散装TCE接触,由于芯的疏水性,系统与界面的TCE侧有明显的划分。 这些多功能系统似乎满足与修复相关的标准,并且相对便宜,并且可能具有环境友好的材料。 优选使用气溶胶工艺以产生负载在碳上的零价铁颗粒。 润滑方法包括制备由单糖或多糖生产的碳微球,碳微球的直径为50nm至6微米,用表面涂层涂覆微球并使用碳微球作为润滑剂。
